January 2012 Report No. 097613024-020-R-Rev0 1
1.0 INTRODUCTION
EastLink is a 39-kilometre motorway running between Donvale in
Melbourne’s north-east to Frankston in Melbourne’s south-east with
two tunnels under the Mullum Mullum Valley. Transfield Services,
who are responsible for operation and maintenance of the road,
commissioned Golder Associates Pty. Ltd. to provide continuous
emission monitoring services for the EastLink motorway project. The
services provided include:
Operations and maintenance services for the EastLink ventilation
stack continuous emission monitoring systems (CEMS)
NATA endorsed emission monitoring reports. Monitoring commenced
on the 29th June, 2008 with the opening of the EastLink motorway.
Results for the sampling period 1st October, 2011 to 31st December,
2011 inclusive are contained in the following report.

2.0 DISCHARGES TO AIR
EastLink has discharges to air servicing two road tunnels.
Discharge Point No. 1 (DP1) services the inbound (Melba) tunnel and
Discharge Point No. 2 (DP2) services the outbound (Mullum Mullum)
tunnel.
The locations of the discharges to air are described in Table 1
and presented in Figure 1.
Table 1: Discharges to Air Discharge Point No. Station Name
Location
1 Western ventilation stack Western end of inbound tunnel
(Melba) - Donvale
2 Eastern ventilation stack Eastern end of outbound tunnel
(Mullum Mullum) – Ringwood
Monitoring equipment is housed in temperature controlled
cabinets located at the base of each of the ventilation stacks.
Particulate and gaseous sample inlets are installed inside the
plenum chamber of each of the ventilation stacks.

4.0 METHODS 4.1 PM2.5 PM2.5 concentrations in the tunnel
ventilation stacks are determined using a 1400 Series Tapered
Element Oscillating Microbalance (TEOM) analyser, located in the
plenum chamber of the ventilation stacks.
Exhaust gas is drawn through a PM2.5 size selective inlet (PM10
WINS head fitted with a PM2.5 sharp cut cyclone (SCC)) at 1 m3/h.
The flow is then isokinetically split into two streams; 1 l/min
stream which passes through the filter on the mass transducer and a
15.7 l/min bypass stream.
The sample stream is heated to 50°C to maintain a low and
therefore relatively constant humidity.
Measurements are made in real-time (2 s intervals) with the
5-minute averages logged. 1-hour averages are then calculated from
the logged data.
The PM2.5 monitoring method is based on the requirements of
Australian Standard AS 3580.9.8, “Methods for Sampling and Analysis
of Ambient Air: Determination of Suspended Particulate Matter –
PM10 Continuous Direct Mass Method Using a Tapered Element
Oscillating Microbalance Analyser”.
4.2 PM10 PM10 concentrations in the tunnel ventilation stacks
are determined using a 1400 Series Tapered Element Oscillating
Microbalance (TEOM) analyser, located in the plenum chamber of the
ventilation stacks.
Exhaust gas is drawn through a PM10 size selective inlet (PM10
WINS head) at 1 m3/h. The flow is then isokinetically split into
two streams; 1 l/min stream which passes through the filter on the
mass transducer and a 15.7 l/min bypass stream.
The sample stream is heated to 50°C to maintain a low and
therefore relatively constant humidity.
Measurements are made in real-time (2 s intervals) with the
5-minute averages logged. 1-hour averages are then calculated from
the logged data.
The PM10 monitoring method is based on the requirements of
Australian Standard AS 3580.9.8, “Methods for Sampling and Analysis
of Ambient Air: Determination of Suspended Particulate Matter –
PM10 Continuous Direct Mass Method Using a Tapered Element
Oscillating Microbalance Analyser”.
4.3 Carbon Monoxide Carbon monoxide concentrations in the tunnel
ventilation stacks are determined by infra-red gas filter
correlation analysers.
Automatic calibrations are carried out daily against a NATA
certified reference gas mixture. Manual calibrations are conducted
at one month intervals.
The carbon monoxide monitoring method is based on the
requirements of Australian Standard AS 3580.7.1, “Determination of
Carbon Monoxide – Direct Reading Instrumental Method”.

4.4 Oxides of Nitrogen Oxides of nitrogen concentrations in the
tunnel ventilation stacks are determined by chemiluminescence gas
analysers.
Automatic calibrations are carried out daily against a NATA
certified reference gas mixture. Manual calibrations are conducted
at one month intervals.
The oxides of nitrogen (NO, NO2 and NOx) monitoring method is
based on the requirements of Australian Standard AS 3580.5.1,
“Determination of Oxides of Nitrogen – Chemiluminescence
Method”.
4.5 Stack Velocity Stack gas velocity was determined using an
optical flow sensor that complies with USEPA Code of Federal
Regulations (CFR 40) Part 75, “Continuous Emission Monitoring”
requirements.

6.0 VENTILATION STACK EMISSION MONITORING PERIOD: 01/10/2011 –
31/10/2011
6.1 Data Capture Data capture is defined as the number of valid
data periods collected divided by the number of available data
periods. Valid data excludes periods where the instrument is
unavailable due to calibration and maintenance and excludes periods
where the data has been rejected due to quality assurance/data
validation procedures.
The data capture statistics for the reporting period 1st October
to 31st October, 2011 are shown in Table 3. Averages were only
collected for those periods where the 5-minute data constituted 75%
data capture.
Section 6.3 provides further information on the reasons for
invalid data periods.

7.0 VENTILATION STACK EMISSION MONITORING PERIOD: 01/11/2011 –
30/11/2011
7.1 Data Capture Data capture is defined as the number of valid
data periods collected divided by the number of available data
periods. Valid data excludes periods where the instrument is
unavailable due to calibration and maintenance and excludes periods
where the data has been rejected due to quality assurance/data
validation procedures.
The data capture statistics for the reporting period 1st
November to 30th November, 2011 are shown in Table 11. Averages
were only collected for those periods where the 5-minute data
constituted 75% data capture.
Section 7.3 provides further information on the reasons for
invalid data periods.

8.0 VENTILATION STACK EMISSION MONITORING PERIOD: 01/12/2011 –
31/12/2011
8.1 Data Capture Data capture is defined as the number of valid
data periods collected divided by the number of available data
periods. Valid data excludes periods where the instrument is
unavailable due to calibration and maintenance and excludes periods
where the data has been rejected due to quality assurance/data
validation procedures.
The data capture statistics for the reporting period 1st
December to 31st December, 2011 are shown in Table 19. Averages
were only collected for those periods where the 5 minute data
constituted 75% data capture.
Section 8.3 provides further information on the reasons for
invalid data periods.

8.2 Results
8.2.1 PM2.5 PM2.5 was continuously monitored and 5-minute
averages logged. The 5-minute average data was then transformed to
1-hour averages for reporting.
PM2.5 (1-hour average) mass rate of emission statistics for the
reporting period are given in Table 20. A plot of PM2.5 (1-hour
average) mass rate of emission for the reporting period is
presented in Figure 14.

8.3 Data Validation and Exceptions Data contained in the report
has been validated against performance and calibration requirements
for each instrument. Data during maintenance and calibration
periods has been removed from the validated data sets. Tables 25
and 26 list the data exceptions for the eastern and western
ventilation stacks respectively. Data during automatic calibrations
of the gaseous atmospheric contaminants has also been removed from
the data sets.

9.0 DISCUSSION
9.1 Comparison with Licence Limits EastLink emissions to air
from the road tunnel ventilation stacks DP1 and DP2 are subject to
the licence requirements contained in Environment Protection
Authority (Victoria) Waste Discharge Licence No. EA 63607.
The maximum measured 1 hour average mass rate for each parameter
is compared with the applicable licence limit in Table 27.
Table 27: Maximum (1 Hour Average) Mass Rate (01/10/2011 -
31/12/2011) Discharge Point No. Discharge Description Compound Mass
Rate (kg/h) Licence Limit (kg/h)
1 Western ventilation stack PM2.5 0.34 2.4
PM10 0.94 2.6
NO2 0.49 3.98
CO 29 112
2 Eastern ventilation stack PM2.5 0.37 2.4
PM10 0.88 2.6
NO2 0.69 3.98
CO 32 112
There were no exceedences of the licence limits for DP1 and DP2
during the reporting period.
Data capture statistics for 2011 year to date (01/01/2011 –
31/12/2011) are presented in Table 28.
